Upcoming Policy Changes
One of the major focal points of Version 1.5 requires that applicants seeking inclusion in the Chrome Root Store must support automated certificate issuance and management. […] It’s important to note that these new requirements do not prohibit Chrome Root Store applicants from supporting “non-automated” methods of certificate issuance and renewal, nor require website operators to only rely on the automated solution(s) for certificate issuance and renewal. The intent behind this policy update is to make automated certificate issuance an option for a CA owner’s customers.
That was absolutely digestible by a 5 year old like me. Many thanks!
